The Heat U.P. Wisconsin program brings dealers together with Lennox Industries to provide families in need with a new hi-efficiency gas furnace for their family. Every year Lennox donates up to 100 ML193 furnaces and participating Lennox dealers like ourselves donate our time and the materials to install them in local homes throughout Wisconsin and the U.P. We are the first State to do this and many are now following suit.

Our Community

In 2012 we installed a new furnace and did major upgrades to the ductwork of great family whose farm came on hard times and they lost their farm and home and had to purchase a foreclosure that had a broken furnace and shoddy inadequate ductwork. In 2013 we installed a new Lennox furnace for a man that had debilitating back problems that prevented him from being able to use his wood furnace to heat his home. With his new gas furnace he no longer has to worry about cutting, splitting or carrying wood into his basement to heat his home.  In 2014 we installed a new Lennox furnace for a family where the husband a veteran was seriously injured in combat and needs to stay near the hospital for his healthcare needs away from his family.  His wife and kids couldn't afford to keep warm in winter with their old original furnace, a problem the 93% Lennox furnace will fix.  We appreciate all the help our employees and the community provides to help us with this every year.  Click the button below to nominate next year’s family so we can provide them with the gift of warmth this winter.

Make A Wish

For every Luxaire product we sell a contribution is made to the Wisconsin Make-A-Wish Foundation for terminally ill children. Luxaire is owned by Johnson Controls a Wisconsin based company and Wisconsin’s largest employer. Johnson Controls has donated over $2 million to the foundation and is constantly increasing that amount.


“Schulz Heating and Cooling helped us solve a heating issue. The service was excellent. The new Lennox furnace is warmer, quieter and heats more efficiently than what we had. The work was completed in one day and the workmen were friendly and helpful. We also had AC installed for the first time. I would recommend their services to anyone looking at upgrading their heating and cooling needs.” Mary L. Keshena, WI

"Very good job and cleanup after!" - J. Eveland

"Thank you again for the prompt and thorough service on the installation of Weil-McLain Ultra Boiler. My wife was worried that we would be without heat and domestic hot water when our out of town relatives were to arrive on Wednesday, with Russ and Ron dedicated with their time spent on Tuesday to make sure this was not the case. Jim and Nathan were also prompt to resolve the minor issues related to the original installation done by another local company 10 years ago. In all, thanks again to the Schulz Family and its team members to make our job a priority, and we can rest easy knowing that the installation was done right, and the follow-up visit to check for leaks, etc. was greatly appreciated, and is a testament to Schulz’s dedication to customer satisfaction." - M. Koepsel
